Subject: Changes to Observations from USRCRN on or about
April 6, 2013
US Regional Climate Reference Network (USRCRN) Precipitation
measurements from southwest region sites will be phased out over
several months beginning on or about April 6, 2013.
The current challenging and uncertain budget environment is
requiring NWS to conduct a thorough review of non-mission
critical functions. The USRCRN was intended to be a nationwide
network of over 500 sites performing high-quality temperature and
precipitation observations at a spatial resolution sufficient to
detect climate variations on a regional scale over the
continental United States. Due to budget constraints, the
deployment of sites was halted after 70 sites had been installed.
Areas covered included Alabama and the southwest region states of
Colorado, Utah, New Mexico and Arizona.
This action is proposed to mitigate the potential release of
hazardous materials from the precipitation sensor should adequate
funds not be available to continue normal operation and
maintenance of the network. Since there are no such environmental
issues with the temperature sensors, temperature measurements at
the USRCRN sites will continue.
Although the observations from the USRCRN sites provide value for
climate monitoring in supplementing observations from other
available observing systems in those areas, the USRCRN systems
are not required for NWS to perform its operational mission.
Because maintenance will be completed at the Alabama sites,
precipitation measurements from these sites are planned to
continue through next fiscal year. In addition, temperature
measurements from all sites are also planned to continue through
the next fiscal year.
